CROSS REFERENCE TO RELATED APPLICATION

This application claims the benefit of U.S. Provisional Application No. 61/791,816 filed on Mar. 15, 2013, which is incorporated by reference as if fully set forth.

FIELD OF INVENTION

The present invention is related to e-commerce.

BACKGROUND

Many companies purchase software as a service (SaaS), platform as a service (PaaS), Infrastructure as a Service (IaaS) or something similar. SaaS is essentially “on-demand software” supplied by software vendors where software and associated data are centrally hosted on the cloud. SaaS software can be accessed by customers using a thin client via a web browser. Similarly IaaS is a model wherein a company outsources the equipment for operation, such as storage, hardware, servers and networking components. PaaS is a model allowing customers to rent hardware, operating systems, storage and network capacity over the Internet. However, many companies and non-profit organizations do not like being tied to a monthly fee. Also, the flexibility to customize to a particular business's needs may be limited based on the rules of the SaaS, PaaS, and IaaS provides.

Methods and apparatus are desired allowing companies the flexibility to enable e-commerce transactions.

SUMMARY

DETAILED DESCRIPTION

When used herein, the term “token” may refer to a sequence of byte data or a string or a file used to authenticate a transaction. A token may be one or multiple encrypted strings, files, passwords, cyphers or other data which may contain information used to perform or authenticate a transaction when sent to payment servers. These tokens may be encrypted using a public-private key encryption system. The vendor or a party with knowledge of the vendor's private key may generate an encrypted token. Alternatively, a payment system or e-commerce site may generate this token on behalf of the vendor.

Disclosed herein are processor-executable methods, computing systems, and related technologies for an automated application programming interface (API). The system and method may use an email server/account to complete an e-commerce transaction (e.g., for items/services/events/donations) for a transfer of funds from a customer to a vendor (e.g. retail site, charity, political organization or other vendor.) While the technologies described herein are discussed using e-mail as an example, they may also be applicable to similar communication mediums, such as SMS and MMS communication channels.

FIG. 1 shows an example system 100 that may be utilized for email based financial transactions. The example system 100 includes a customer device 150, a vendor server 120, a payment server 140, and a banking server that may communicate over one or more wired and/or wireless communication networks 110. The wired or wireless communication networks 110 may be public, private or a combination of public or private networks.

The customer device 150 may be, for example, a cellular phone, a smartphone, a desktop computer, a laptop computer, a tablet computer, or any other appropriate computing device. The customer device 150 includes a processor 151, memory 152, a communications unit 153, a display unit 154 and web browser unit 155, which may communicate data to/from the web server module(s) in the vendor server 120 and payment server 140. The web browser unit 155 may include and/or communicate with one or more sub-modules that perform functionality such as rendering HTML (including but not limited to HTML5), rendering raster and/or vector graphics, executing JAVASCRIPT, and/or rendering multimedia content.

Alternatively or additionally, the web browser unit 155 may implement Rich Internet Application (RIA) and/or multimedia technologies such as ADOBE FLASH and/or other technologies compatible with Internet based communications. The web browser unit 155 may implement RIA and/or multimedia technologies using one or web browser plug-in modules (e.g., ADOBE FLASH), and/or using one or more sub-modules within the web browser unit 155 itself. The web browser unit 155 may display data on one or more display devices (not depicted) that are included in or connected to the customer device 150, such as a liquid crystal display (LCD) display or monitor. The customer device 150 may receive input from the user of the customer device 150 from input devices (not depicted) that are included in, or connected to, the customer device 150, such as a keyboard, a mouse, a microphone or a touch screen, and provide data that indicates the input to the web browser unit 155.

The vendor server 120 may include an HTTP server module 121, a token generator 122, a button generator 123, a processor 124, memory 125, a payment gateway 126 and a communications unit 127.

The HTTP server module 121 provides a website that may be accessed by a customer device 150. The HTTP server module 121 may implement the HTTP protocol, and may communicate Hypertext Markup Language (HTML) pages and related data from the website to/from the customer device 150 using HTTP. The vendor server 120 may be connected to one or more private or public networks (such as the Internet), via which the HTTP server module 121 communicates with devices such as the customer device 150. The HTTP server module 121 may generate one or more web pages and may communicate the web pages to the customer device 150, and may receive responsive information from the customer device 150.

The HTTP server module 121 may be, for example, an NGINX server APACHE HTTP server, a SUN-ONE Web Server, a MICROSOFT INTERNET Information Services (IIS) server, and/or may be based on any other appropriate HTTP server technology. The vendor server 120 may also include one or more additional components or modules (not depicted), such as one or more load balancers, firewall devices, routers, switches, and devices that handle power backup and data redundancy.

The payment gateway 126 may be a proprietary service that directly connects with the payment processors, such as banking server 160 to handle the credit card data, and authorize credit card payments.

The token generator 122 may generate tokens for use in e-commerce transactions. Tokens may be encrypted sequence of data which contain information to perform a transaction when sent to the payment server(s) 140. Additionally or alternatively, a token may be one or multiple encrypted strings, files, passwords, cyphers or other data which may contain information used to perform or authenticate a transaction. A token may include one or more of the following parameters or other parameters not listed below:

-   -   a) private-key: The private key provided by the payment server         140.     -   b) public-key: Payment server's 140 public key, provided by the         payment server 140.     -   c) partner-id: The partner ID provided by the payment server.     -   d) environment: The environment the vendor wants to generate         buttons for. This distinguishes whether the token is being used         in a testing environment or in the live environment (and running         real transactions).     -   e) config: The path to a configuration file in yml format. This         may hold a default set of information, e.g., private_key,         public_key, partner_id, and other information—so they don't have         to be entered separately each time a token is generated. The         config field may also contain information specific to an offer         (e.g. dollar amount) or a customer (like the card token) if         multiple tokens are being generated with similar components.     -   f) type: The type of token to generate (site, email, universal).         There are multiple types of tokens that a token generator can         generate and decode. For example, site tokens may be used for         website transactions, email tokens for two-click email payments,         and universal tokens for email validations.     -   g) card: The card token associated with the recipient of this         token. When a customer is registered with the payment server         140, the vendor receives a credit card token—a unique identifier         that references the specific card associated with that customer         and vendor. When the vendor is generating a token to submit to         payment server 140, they may include the card token as a         customer identifier.     -   h) email: The email associated with the receipt of this token.     -   i) URL: The Signup URL the recipient should go to if customer         doesn't have payment information registered with payment server         140.     -   j) amount: The amount a user should be charged for the         transaction the token is generated for.     -   k) user-data: Data to pass back as a reference. This data may         include custom data that the vendor may want to pass through the         payment server 140 and receive back when a transaction has         completed. It may include an item reference number or SKU,         customer address, or other piece of data that is not required by         payment server 140 to complete a transaction, but that the         vendor wants associated with that transaction.     -   l) expires: Expiration date for token, integer value of seconds         since epoch.     -   m) header-user-agent: The HTTP_USER_AGENT from the request         header. HTTP headers are sent as part of a request from a         customer's web browser unit 155 for a piece of information.         These headers define the parameters that the web browser unit         155 is expecting to get back. The user-agent is the identifier         of the software that is submitting the request—typically the         identifier of the web browser unit 155 that is requesting the         content.     -   n) header-accept-language: The HTTP_ACCEPT_LANGUAGE from the         request header. The accept-language is the acceptable language         for the response—e.g. the language in which the web browser unit         155 is requesting the content be sent back.     -   o) header-accept-charset: The HTTP_ACCEPT_CHARSET from the         request header. The accept-charset is the character sets that         are acceptable for the response—e.g. the character set in which         the web browser unit 155 is requesting the content be sent back.     -   p) ip-address: The IP address of the token recipient.

To confirm an e-commerce transaction via email, the customer sends an email embedded with a token to the payment server's 140 address. The system 100 is designed to allow the vendor flexibility to offer deals for a limited time or number or responsive to available inventory. For example, the token may be configured to expire by default after two weeks, or any predetermined time, or never expire. The vendor server 120 may be configured to extend or shorten the expiration time of a particular offer associated with a token without resending an email or generating a new token. Also, the vendor server 120 may send email updates for an offer associated with a token. This may be predetermined, or may be later set, depending upon demand by customers. Additionally, the vendor server 120 may generate groups of token values that may automatically invalidate members of the group when one token is processed. This is useful when sending out multiple tokens via email to a single customer or when sending out tokens to multiple customers, but when the vendor wants only one or a predetermined number of tokens to be processed. Therefore when these predetermined number of tokens are used, the other tokens are invalidated, effectively rescinding the offered deal. The vendor server 120 may further be configured to send email notifications that the previously submitted token is now invalid.

The button generator 123 may create cross-client and cross-browser compatible buttons for e-commerce transactions. In one embodiment, the button generator 123 may include the token generator 122 to automatically generate an associated token for each button that is created. As discussed in greater below, the token generator 122 and button generator 123 may be configured to access an API that is stored in memory 125 and controlled by processor 124.

The vendor server 120, using the API, as disclosed herein may communicate with the payment server 140 to provide information to the button generator 123 and the token generator 122. A button and an associated token, generated by the button generator 123 and/or the token generator 122 may be embedded on a web page created by the HTTP server module 121.

The memory 125 may be configured to store information associated with e-commerce transactions. This may include inventory information, information used to generate web pages, customer information, and other e-commerce data.

The payment server 140 may include an HTTP server module 141, a token generator 142, a processor 143, memory 144, payment gateway 145 and a communications unit 146. While only one vendor server 120 is shown communicating with the payment server 140, this is shown as only an example but there may be many payment servers 140. Payment server 140 may communicate with multiple vendor servers 120. A customer, wishing to use the services of the payment server 140, may register his/her email address and payment information with the payment server 140. Similarly, vendors may register with the payment server 140. The payment server 140 may provide the vendor server 120 with a public key and private key to be used in token transaction in accordance with the methods described herein. When a transaction is attempted, the payment server 140 decodes the token, authenticates the sender of the email, and may process the transaction. While the payment server 140 is depicted as a separate entity in FIG. 1, this is shown as an example only. The payment server 140 may be controlled and/or co-located with the vendor server 120, the banking server 160.

The banking server 160 may be controlled by a third party system bank. The payment server 140 may communicate with the banking server 160 to verify that the customer has adequate funds or credit for the requested purchase. For example, the banking server 160 may be a controlled by VISA, AMERICAN EXPRESS, MASTERCARD or any other bank or banking or financial network that a customer may use for online payment. The banking server 160 may be a server for virtual currencies, such as BITCOIN, etc.

FIG. 2 shows a flow diagram for a method 200 for implementing an API interface. A customer, using a customer device 150 may attempt to access a vendor website (step 205). The vendor website may be a website selling retail goods or services or soliciting donations. The vendor website is redirected to the payment server 140, to grant the vendor access to the customer's account information (step 210). Once the customer is redirected to this website, the customer logs into the payment server account and authorizes the vendor to access the customer's account information (step 215). The payment server 140 redirects the customer back to the vendor server 120 with an access code (step 220). The vendor server 120 requests an authorization token with the previously sent access code (step 225). The payment server 140 sends the vendor server 120 an authorization token (step 230). The vendor server 120 may then submit an authorization token with future API transaction requests (step 235).

FIG. 3 shows communication between a payment server 140 and a vendor server 120. Referring to FIG. 3 the API allows a vendor server 120 to request permission from a user to perform operations using their account, securely retrieve basic account information if the user has granted permission, such as: 1. Avatar URL; 2. First Name; 3. Last Name; 4. Email Address; and 5. Username. This is performed by the API transmitting an authorization request to the payment server. As an example, in FIG. 3, the vendor server may use OAuth 2.0. OAuth is an open standard for authorization that allows the vendor server 120 to access the payment server 140 resources on behalf of the customer. OAuth may also provide a process for customers to authorize third-party access resources without sharing their credentials (typically, a username and password pair), using user-agent redirections.

Also shown in FIG. 3, the API also permits the vendor server 120 to securely generate two-click payment buttons for a customer that has granted permission, from a list of recipient email addresses. The vendor server 120 transmits an account information request to the payment server 140, for an account associated with a customer. The payment server 140 responds by providing the vendor server 120 with a customer's account information, such as email, username, first name, last name, and an avatar URL. The vendor server 120 may request a button, and the API provides information for the inclusion of payment buttons in content not being generated directly by payment server 140.

The API enables an exchange of information between any business entity and payment server 140, extending a business' application's capabilities with two-click payment technology.

The API may perform an entire transaction invoicing system, and may be applied to any similar email payment technologies. In addition, the API may be used within other companies email marketing systems for the creation of different workflows.

With authentication, there may be a secure workflow, but the email may not be encrypted. In an alternative embodiment, the email may use DomainKeys Identified Mail (DKIM) and/or Sender Policy Framework (SPF) technology. DKIM provides a method for validating a domain name identity that is associated with a message through cryptographic authentication. SPM is an email validation system designed to prevent email spam by detecting email spoofing. If DKIM and/or SPF are used for authentication, then tokens unique to each user may be unnecessary.

The API provides an OAuth 2.0 authentication system and a number of endpoints that enable its users to extend an application's capabilities with, for example, a two-click transaction. The system may comprise an API developer dashboard that provides access to client configurations as well as statistical information allowing a user to have access to API performance and status on a real time basis. For example, the API Dashboard may comprise a user interface to manage API information. Clients may be able to reset security keys, add OAuth client and update Postback URL.

FIGS. 4-11 show example web pages that may be displayed by the web browser unit 155 of the customer device 150. As will be described in detail below, the web pages may include display elements which allow the user of the customer device 150 to complete e-commerce transactions from a vendor using the disclosed API, using one or more emails. The web pages may be included in a web browser window that is displayed and managed by the web browser unit 155. The web pages may include data received by the web browser unit 155 from the vendor server 120 and/or the payment server 140. The web pages may include payment transaction information.

The web browser window may include a control area 400 that includes a back button 402, forward button 403, refresh button 404, home button 405, and address field 406. The control area 400 may also include one or more additional control elements, such as bookmark page etc. The user of the customer device 150 may select the control elements in the control area 400. The selection may be performed, for example, by clicking a mouse or providing input via keyboard, touch screen, and/or other type of input device. When one of the control elements is selected, the web browser unit 155 may perform an action that corresponds to the selected element. For example, when the refresh button 404 is selected, the web browser unit 155 may refresh the page currently viewed in the web browser window.

FIG. 4 is an example web page 410 for a customer to set up account with the payment server. As shown in FIG. 4, the web page may include multiple input fields 411-414. Input fields 411-413 request a customer to enter email and password information to be associated with a customer account to be created. As the customer device 150 receives input for the input fields 411-414, the web browser unit 155 may store one or more data structures that reflect the selections made in the input fields. Further, as the selections are updated, the web browser unit 155 may update the web page 410 to indicate additional, or more specific, questions that may be associated with the selections. When the user selects input field 414, if there are no errors in the transmission, the customer is taken to a subsequent web page, e.g. web page 510.

FIG. 5 is an example web page 510 for a customer to enter billing information into the payment server 140. As shown in FIG. 5, the web page 510 may include multiple input fields 511-516. Input fields 511-515 solicit customer responses to questions regarding the customer's billing information, or more specifically, in the example shown, a billing address. As the customer device 150 receives input for the input fields 511-515, the web browser unit 155 may store one or more data structures that reflect the selections made in the input fields. Further, as the selections are updated, the web browser unit 155 may update the web page 510 to indicate additional, or more specific, questions that may be associated with the selections. When the user selects input field 516, if there are no errors in the transmission, the customer is taken to a subsequent web page, e.g. web page 610.

FIG. 6 is an example web page 610 for a customer to enter credit card information into the payment server 140. As shown in FIG. 6, the web page 610 may include multiple input fields 610-617. Input fields 611-616 solicit the customer to submit credit card information. As the customer device 150 receives input for the input fields 610-617, the web browser unit 155 may store one or more data structures that reflect the selections made in the input fields. Further, as the selections are updated, the web browser unit 155 may update the web page 610 to indicate additional, or more specific, questions that may be associated with the selections. When the user selects input field 617, if there are no errors in the transmission, the customer is taken to a subsequent web page, e.g. web page 710.

FIG. 7 is an example web page 710 for a customer to agree to terms of service of the payment server 140. As shown in FIG. 7, the web page 710 may include input buttons 712 and 713. This page may or may not be optional. Once the customer has reviewed the Terms of Service in field 711, the customer may select input button 712 or 713. As the customer device 150 receives input for the input buttons 712 or 713, the web browser unit 155 may store one or more data structures that reflect the selections made in the input buttons. Further, as the selections are updated, the web browser unit 155 may update the web page 710 to indicate additional, or more specific, questions that may be associated with the selections. When the user selects input field 713, if there are no errors in the transmission, the customer is taken to a subsequent web page, e.g. web page 810.

FIG. 8 is an example web page 810 for a soliciting permission to share information with a third party. As shown in FIG. 8, the web page 810 may include input buttons 811 and 812. A question is presented on web page 810 requesting the customer's permission to set third party account access for use with the email payment system. As the customer device 150 receives input for the input buttons 811 or 812, the web browser unit 155 may store one or more data structures that reflect the selections made in the input buttons 811, 812. Further, as the selections are updated, the web browser unit 155 may update the web page 810 to indicate additional, or more specific, questions that may be associated with the selections.

FIG. 9 is an example web page 910 showing a customer device 150 purchasing an item from a vendor server 120 using the API. As shown in FIG. 9, the web page 910 may include input buttons 911 and 912. In the example shown, the customer has selected input button 911 to indicate interest in the Aurora flower available for sale. As the customer device 150 receives input for the input buttons 811 or 812, the web browser unit 155 may store one or more data structures that reflect the selections made in the input buttons. Further, as the selections are updated, the web browser unit 155 may update the web page 810 to indicate additional, or more specific, questions that may be associated with the selections. As shown in FIG. 9, the web browser unit 155 has opened a pop-up window 913, with input buttons 914 and 915. The pop-up window 913 allows the customer device 150 to confirm the purchase with input button 915 or cancel the purchase with input button 914.

FIG. 10 is another example web page 910 showing a customer device 150 purchasing an item from a vendor server 120 using the API. In the example shown, the customer selected input button 915 to confirm the purchase of the Aurora flower in FIG. 9. As shown in FIG. 10, the web browser unit 155 has updated web page 910 to show status indicator 916. Status indicator 916 notifies the customer that the email checkout system, operated by the API has been engaged.

FIG. 11 is another example of web page 910 showing a customer device 150 purchasing an item from a vendor server 120 using the API. In the example shown, the customer has previously selected input button 915 to confirm the purchase of the Aurora flower in FIG. 9. As shown in FIG. 11, the web browser unit 155 has opened a pop-up window 917, with input button 918. The pop-up window 917 confirms that the vendor server 120 was able to communicate with the payment server 140 to purchase the selected item. In this scenario, a customer may receive an offer email that may be generated by the vendor server 120. Or the vendor server 120 may generate an offer via a website. When a customer completes a transaction, as shown in FIG. 11, either the vendor server 120 or the payment server 140 may generate a receipt email to the customer, based on preference settings.

To perform a transaction, such as the transaction showed in FIGS. 8-11, an application may generate a “client” record for each of its environments. The vendor server 120 copies keys for each client and securely stores them for later use in application development.

A vendor logs in and creates a client, this may allow them begin processing authentications.

Once the vendor server 120 has created a client, customers, operating customer devices 150 connect their accounts to a vendor server's 120 application e.g. via OAuth 2.0. This may allow the payment server 140 to make basic account information, such as the information entered in input fields 411, 511-515, and 611-612 to be available to the vendor server 120.

This basic information may be available to the vendor server 120 by transmitting a request. This request may be, e.g. “GET/api/account/show”. To prevent unauthorized requests, the request may require an access token.

The payment server 140 may respond as follows:

{ “email”: “api@atpay.com”, “username”: “api@atpay.com”, “name”: “API User Example”, “first_name”: “API User”, “last_name”: “Example”, “avatar”: “https://secure.atpay.com/images/missing_avatar_small.png” }

The following parameters may be entered in a request:

Param name Description oauth_token The Access Token corresponding to the user you wish to required get info for.

-   -   Value: String

Referring back to FIGS. 9-11, input buttons 911 and 912 are examples of payment buttons. The payment button is the nucleus of @Pay's technology. When included in an outgoing email to a member, it packages the two-click transaction and enables seamless email checkout from within the customer's email client. When included in an outgoing email to a non-member, it provides the ability to quickly sign up with the payment server 140 and process a transaction with a vendor server 120 through the web interface. The API enables the vendor server 120 to generate payment buttons for inclusion in outgoing emails. The API allows the vendor server 120 to create HTML Payment Buttons. This endpoint requires the ‘buttons’ scope. To create a button, the API associated with the vendor server 120 may generate a request from the payment server 140. A request may include the following parameters: access token, amount, and email.

An example scenario is shown below. In this scenario bob@test.com has an account with the payment server 140 while tim@test.net does not.

An example response, when a request for a button sent is as follows:

[ { “email”: “bob@test.com”, “amount”: “20.00”, “button”: <key_button> }, { “email”: “tim@test.net”, “amount”: “20.00”, “button”: <link_button> } ]

The difference between a key_button and a link_button is the interpolation of {{url}} in the Button Template. A key_button {{url}} is replaced with a mailto link, while a link_button puts a regular link in the {{url}} spot.

The API at the vendor server 120 may generate mailto links for any email address associated with a customer account with the payment server 140. Any address that is not identified by the payment server 140 generates a link which may be used to make a purchase, but the customer is directed to the payment server 140 website to complete the purchase and sign up.

Parameters associated with a button generated by the API may include the following:

Params

Param name Description amount For example, the amount of the transaction email A list of email addresses that will be receiving the message. oauth_token The Access Token ID corresponding to the user you wish to build buttons for.

As discussed above, the API may include an authorization procedure. For example, the API may use OAuth2 for authorization and authentication to all available endpoints.

The vendor server 120 may include an application to create a client record on the payment server 140, granting it API access and identifying it with a pair of cryptographic signatures. The vendor server 120 may create multiple client records for each environment in the application.

A customer, using a customer device 150 may access the vendor server 120 via a website. The customer connects their account with the vendor server's 120 application, granting the vendor server 120 the ability to take action on behalf of the customer part over resources stored at the payment server 140. This action may be similar to the “Log in with” options provided by services such as GOOGLE, FACEBOOK and GITHUB. The vendor server's 120 application begins this authentication process by redirecting to the authorization endpoint with information about the client record identification, and predetermined redirect URLs. The vendor server's 120 authorization client library (e.g. OAuth 2.0) may perform the generation of this authorization URL.

If the customer is a registered with the payment server 140, but not logged in, they will be prompted to do so. After successfully authenticating customer credentials, the customer may be redirected to another page on the payment server's 140 website where the customer will be prompted to enter an input to either Accept or Deny an application access to the scopes the vendor server 120 requested. After selecting an option, customer is redirected back to the vendor server 120, and the vendor server 120 may request an authorization token with the code sent by the payment server 140 in the redirect. This token is used in subsequent requests by the vendor server 120 application to access the payment server's 140 API endpoints.

The life of the token may not be related to the session state of the customer. The customer may log in or out of the payment server 140 or the vendor server 120 application and not affect the usability of the token itself. This allows the vendor server 120 to perform requests with this token in scheduled tasks and background processes.

The payment server 140 API may be configured to allow a vendor server 120 to refresh a token when it expires, and handle invalid token requests with authorization on part of the customer.

An API core controlled by the processor 124 may generate a security key that may be as a mailto link. The key is validated based on whether it matches the email that it came from, and is tied to no transaction or workflow. Its validation is just a validation, and is not related to a transaction—it may provide the ability to process a two-click e-commerce transaction. The key may be linked to autopilot or built into one or more applications.

FIG. 12 shows an example email generated by a vendor server 120 using the API. As described above, the API allows a vendor to request two-click payment buttons 1211 and 1221 for inclusion in an HTML formatted email message 1200. As shown in FIG. 12, the email message 1200 includes an email header 1202 which includes “from”, “subject”, “date”, “to” and “reply-to” fields. The email includes two offers, an offer for an apple blossom 1210 and an offer for an aurora 1220. Each offer has an associated payment button 1211 and 1221. Payment buttons 1211 and 1221 may each be embedded with a link that includes a token. The token may include information identifying the product and purchase price of the offer it is associated with. By selecting pay button 1211 or 1221 an email client associated with the customer device 150 may generate a response email that is addressed to the payment server 140. The response email may include information allowing the payment server 140 to complete the transaction, including a token and information from the email header 1202.
